There is no reason to think that an attachment will contain text
subtitles. Furthermore, attachments are exported in extradata, so the
AV_CODEC_ID_TEXT decoder would not do anything useful with them anyway.
mov_mdhd_language_map table doesn't contain ISO 639 codes for some of
the languages. I added a few which have no contradictory mappings

Unlike avcodec_default_get_buffer2(), this version does not allocate more than
what the lavu image helper functions consider should be allocated for a given
frame.
Since the get_buffer2() documentation does not require any kind of buffer
padding for any of the planes, this should help detect bugs in our DR1 decoders
if they read beyond the end of the buffer, simulating what some library users
might experience when they use their own custom get_buffer2() implementations.

Y, U, V data is loaded at the end of the current iteration for the next
iteration.
It results in memory access past the frame data on the last iteration
(that data is never used after the loading).
So load data at the start of the iteration, so that only useful data is
loaded.

Add support for max frame size:
- max_frame_size (bytes) to indicate the max allowed size for frame.
Control each encoded frame size into target limitation size by adjusting
whole frame's average QP value. The driver will use multi passes to
adjust average QP setp by step to achieve the target, and the result
may not strictly guaranteed. Frame size may exceed target alone with
using the maximum average QP value. The failure always happens on the
intra(especially the first intra frame of a new GOP) frames or set
max_frame_size with a very small number.
example cmdline:
ffmpeg -hwaccel vaapi -vaapi_device /dev/dri/renderD128 -f rawvideo \
-v verbose -s:v 352x288 -i ./input.yuv -vf format=nv12,hwupload \
-c:v h264_vaapi -profile:v main -g 30 -rc_mode VBR -b:v 500k \
-bf 3 -max_frame_size 40000 -vframes 100 -y ./max_frame_size.h264
Max frame size was enabled since VA-API version (0, 33, 0), but query
is available since (1, 5, 0). It will be passed as a parameter in picParam
and should be set for each frame.

Normally, both the source and dest frame would have only the old API fields
set, only the new API fields set, or both set. But in some cases, like when
calling av_frame_ref() using a non reference counted source frame where only
the old channel layout API fields were populated, the result would be the dst
frame having both the new and old fields populated.
This commit takes this into account and fixes the checks by calling
av_channel_layout_compare() only if the source frame has the new API fields
set, and doing sanity checks for the source frame old API fields if the new
ones are not set.

On macOS, code-signing information for executables (including those signed
automatically by the linker) is cached by the system on a per-inode basis.
The cp(1) tool will truncate and overwrite an existing file if present,
so we need to delete it first to avoid strange crashes.
See https://developer.apple.com/documentation/security/updating_mac_software
The VideoToolbox hwaccel needs the entire NAL (including the stop bit),
but ff_h2645_packet_split may remove it. Detect this case by looking for
bit counts divisible by 8 and insert a stop-bit-only 0x80 byte.

This commit moves some of the functionality from avfilter/colorspace
into avutil/csp and exposes it as a public API so it can be used by
libavcodec and/or libavformat. It also converts those structs from
double values to AVRational to make regression testing easier and
more consistent.

This patch adds code to support specializations of the hscale function
and adds a specialization for filterSize == 4.
ff_hscale8to15_4_neon is a complete rewrite. Since the main bottleneck
here is loading the data from src, this data is loaded a whole block
ahead and stored back to the stack to be loaded again with ld4. This
arranges the data for most efficient use of the vector instructions and
removes the need for completion adds at the end. The number of
iterations of the C per iteration of the assembly is increased from 4 to
8, but because of the prefetching, there must be a special section
without prefetching when dstW < 16.
This improves speed on Graviton 2 (Neoverse N1) dramatically in the case
where previously fs=8 would have been required.
before: hscale_8_to_15__fs_8_dstW_512_neon: 1962.8
after : hscale_8_to_15__fs_4_dstW_512_neon: 1220.9
